The game at Hillsborough was goalless when the Portuguese decided to throw caution to the wind by replacing midfielder Ross Wallace with the tall striker with just over half an hour to go.

It would prove to be an important switch as it was the Austrian making a nuisance of himself following Pierluigi Gollini's poor clearance that led to Fernando Forestieri receiving the ball and tucking home the winner five minutes from time.

And Carvalhal has explained that the tactical reshuffle that came from bringing the 27-year-old on inspired a turnaround in how the game was playing out.

"In the second half we started well but, because we didn't score, Aston Villa started to create some problems," he told the Star.

"At that moment, we had two options. I could have put another player in midfield to close the spaces and tried to play on the counter attack as Aston Villa were controlling the game.

"But we took a risk as we wanted to win the game. We decided to put [Atdhe] Nuhiu on and we were more dangerous again."

While Carvalhal will want to avoid his squad getting carried away following the victory, the game allowed them to showcase arguably their biggest strength, and that is the variety they boast in attack.

Although losing Steven Fletcher to injury in the early stages was certainly less than ideal, it meant that ultimately, Wednesday had all four of their main forwards on the pitch at some stage.

And given that they each bring something different to the table - Nuhiu and Fletcher offer a more physical presence, while Hooper and Forestieri are capable of wonderful finishes, while the latter can adopt a playmaker-type role with ease also - it seems highly likely that they will have no problem finding goals this season.
